There are four over-the-counter oral medications that can kill fleas on your dog. If, for some reason, you are considering using one on your dog, you'll want to know what they are and how they're used. As always, exercise caution.

Last month, in Bravecto, Nexgard, or Other: Which Oral Flea Control Should You Use?, we described the five oral medications that veterinarians may prescribe to stop or prevent a dogs flea infestation. This month, well describe the four oral medications that kill fleas on dogs and are available to owners as over-the-counter (OTC) products  no prescription necessary. As with last months installment in this mini-series on flea-control options, the descriptions of these products should not be taken as a recommendation or endorsement.
